Who first invented lithium batteries?

"Lithium battery" is a type of battery that uses lithium metal or lithium alloy as a negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by GilbertN. Lewis. In the 1970s, M.S. Whittingham proposed and began to study lithium ion batteries. Due to the very lively chemical properties of lithium metals, the processing, preservation, and use of lithium metals require very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and can be charged. The fifth-generation lithium metal battery of rechargeable batteries was born in 1996, and its safety, specific capacity, self-discharge rate and performance price are better than those of lithium-ion batteries. Due to its own high-tech requirements, companies in only a few countries are now producing this lithium metal battery.

In 1780, Luigi Galvani, an anatomy professor at the University of Bologna in Italy(September 9, 1737-December 4, 1798), did an anatomical study of the muscle movement of frog legs. He discovered in the experiment that at the same time as the motor discharge, If the frog leg nerve is touched with a metal scalpel, the frog leg muscles immediately contract. In order to find out the reason for this phenomenon, it was accidentally discovered in further experiments that if two metals were used to touch the muscles and muscles of the frog's legs, the frog's legs would also Twitch when the other end of the two metals touched. Gavani believes that this is caused by the presence of a "neuroelectric fluid" in frogs, which can make nerves and muscles move. The brain is an important organ that secretes electrical fluids.

The Italian physicist Alessandro Vlota(February 18, 1745-March 5, 1827) studied the discovery of Galvani in 1792. He found that the generation of electricity did not require animal tissue. In 1793 he denied the existence of animal electricity. He believes that the electricity found by Galvani is generated by the contact of two different metals. He believes that the pumping of the frog's legs is a sensitive reaction to the current, which is due to the fact that the two metals are inserted into the solution provided by the muscles. And form a loop.

In 1799, Volta used copper sheets, paper and zinc sheets impregnated with salt water to overlap in turn, creating the earliest Volta reactor to obtain continuous current. In 1800 he announced the principle of batteries discovered between 1795-1796. In 1801 he demonstrated the Volta reactor for Napoleon I. Napoleon awarded him a gold medal and called him Earl.

In 1799, Volt immersed a zinc plate and a silver plate in salt water and found that there was a current passing through the wire connecting the two metals. So he folded a large number of pieces of zinc and silver between the sheets of fluff or paper impregnated with salt water. When you touch both ends with your hand, you will feel a strong electric shock. Volt used this Fangfachenggong to make the world's first battery, the "Volt Reactor." This "Volt reactor" is actually a series of batteries. It became an early electrical experiment and a source of electricity for Telegraph machines.

In 1803, German chemical Jialiteer made a battery.

In 1836, the British chemist J.F. Dannieer produced the first classical primary battery. One of the disadvantages of Volt reactors is that the current is rapidly reduced due to polarization. The battery he found was a porous ceramic pot(starting with animal membranes) that separated the electrode copper rod immersed in copper sulfate from the zinc rod. It can provide longer stable currents than previous batteries.

In 1859, the French physicist Prant produced the first practical lead-acid battery. He includes two spiraling lead skins, separated by rubber, immersed in 10 % sulfuric acid solution, and then fed an electric current, so that one of the lead skins is plated and the other lead skin becomes a rough porous surface. This battery has a higher electromotive force than any battery at the time. However, due to the complex and lengthy process of processing and molding, it is difficult to mass-produce and is not taken seriously.

In 1865, the French chemist Lucranche produced the first dry battery. He used conductive ammonium chloride solutions, zinc and graphite as electrodes, and used manganese dioxide as a depolarizer. This type of battery is inconvenient due to the use of ammonium chloride solutions.

In 1881, the French chemist C.A. Volt reformed Prandt's lead battery. He avoided the molding process and coated it directly on the lead plate, which caused the lead battery to attract the interest of the business community. It was soon mass-produced and applied in the process of automobiles, radio equipment, and electrochemical experiments, becoming a common use. Important power supply.

In 1888, the chemist Qiasinier improved the battery of Lucranche. He replaced his solution with moist ammonium chloride and replaced the container with zinc skin. It was used in one fell swoop and was widely used.

The invention of the primary battery dates back to the late 18th century, when the Italian biologist Gavani was conducting a famous frog experiment. When he touched the frog's leg with a metal scalpel, he discovered that the frog's leg would Twitch. The famous Volt believes that this is caused by the electric current generated between the metal and the frog leg tissue fluid(electrolyte solution). In 1800, Volta designed a device called a Volt reactor. Zinc was negative, silver was positive, and salt water was used as an electrolyte solution. In 1836, Daniel invented the world's first practical battery and used it for early railway lights.

Lithium batteries were first used in pacemakers. Lithium batteries have the advantages of extremely low self-discharge rates and flat discharge voltage, allowing pacemakers implanted in the human body to operate for a long time without recharging. Lithium batteries generally have a nominal voltage of more than 3.0 volts, which is more suitable for integrated circuit power supplies. Manganese dioxide batteries are widely used in calculators, digital cameras, and watches.
